How we score ↗How big and forgiving the barrel is — based on barrel length, construction (one- vs two-piece, alloy vs composite), and how it plays on balls hit off the center. A primary driver of the overall score.
Raw exit velocity and distance. We use measured numbers from freely available independent testing when they exist; otherwise construction and consensus, judged against the certification’s performance ceiling. A primary driver of the overall score.
Comfort and feedback on contact — vibration dampening from the knob/connection, the sting of a stiff one-piece vs a smooth two-piece, and the sound off the barrel. A primary driver of the overall score.
How well it holds up and how the company stands behind it — documented cracking/denting reports, cold-weather behavior, and the brand’s real warranty record. Good to know, but weighted lightly in the score.
Our take on price-for-performance — the overall package weighed against its cost and what comparable bats run. Shown for context; it is NOT factored into the overall score (price changes too often and is personal).
Why this score: First-pass rating from construction, load profile and the brand's slowpitch platform. We'll confirm with testing.
Our Review
The Cobalt Blue is the two-piece flagship of the Gridlock line, and the one we'd hand most power hitters: a full 13" X2A barrel for maximum hitting surface, a loaded end weight, and Modulated Handle Technology in a high-flex profile that loads and releases through the swing while soaking up contact shock. The half-ounce weight steps (25.5/26/26.5) let you dial swing weight tighter than most lines allow. Certified USSSA/NSA/ISA with a real one-year warranty. This is a preliminary first-pass rating from the bat's build, platform and class; we'll firm it up with real game feedback.
